But some mystery remains, because now Lauren appears to have just blue streaks, sans the pink that was also there when she first wrote about colorful hair tips for her beauty blog, The Beauty Department (not to be confused with our own Girls in the Beauty Department, naturally! Oh, Lauren. We remain so flattered.)

That's not all, though. Look at Lauren's blue "ombre" manicure--meaning each nail is a different shade within the same color family. She has blogged about the ombre nails trend; it appears Lauren is determined to really practice what she preaches on that site! And practice it all at once. (She's even got some mini braids going on in the above pic. Whew, I am exhausted just contemplating all these trends at once! I think I need to go take a nap.)

So what do you think? I just can't wait to hear. Love the hair? The nails? What about both together?
